The nut tree was a restaurant/ destination that became something of an icon for people driving across the state on I80. It was located in the town of Vacaville, about 60 miles east of SF and 20 miles west of Sacramento. It was traditional to stop there for a meal on the way to Lake Tahoe.
It was kind of a unique place. It had a little airport, a little amusement park, and really big restaurant and gift store, a real tourist trap of a deal. A little train ran back and forth from the airport to the restaurant.
In the sixties one of the original owners commissioned Edward Chavez, a master model maker to build a series of 1:10 and 1:12 scale models, mostly of subjects between the wars. These are big models, made from metal, wood, fabric and wire. I think that they are tremendous.
In 1996 the place was sold and torn down and became just another ugly and pointless strip mall along the freeway. The aircraft went to the Aviation Museum at SFO, which is a great place in the new terminal in a room that is a scaled down version of the original departure hall.
Here's the Condor. The model has an 83" wingspan.
Sorry it's so small.
